Cincinnati sets record low Tuesday morning

Greater Cincinnati set a record low temperature Tuesday morning, sinking lower than one that was only in place for a year.

It was 50 degrees at the Cincinnati/Northern Kentucky International Airport at about 7 a.m. Tuesday, said Jim Lott, a meteorologist at the National Weather Service in Wilmington. The record set on this date last year was 54 degrees.

Normal temperatures for this time of year are typically around 85 degrees, Lott said, but a cold front form the north -- the second this month -- has cooled things down.

"It's a cold high pressure system that came down from Canada," he said. "The cold front came though Sunday night and the air mass is just going to sit over us for the next several days."

The high Tuesday is expected to be 76 degrees, and humidity will remain low, as the air mass is fairly dry, Lott said.

"It is a little unusual. We've just had back-to-back cold high pressure systems dropping out of Canada," Lott said. "It happens from time to time, but these two just came close together. it is unusual for it to be this cool twice in July."

Temperatures are expected to gradually rise through the rest of the week, and begin to approach normal by the beginning of August.

Tuesday will be mostly sunny, and temperatures overnight will get down to about 56 degrees.

There's a slight chance of showers and thunderstorms after 1 p.m. Wednesday, and the high will reach 79.

The rest of the week will be sunny with highs near 81 and lows dropping to about 61, according to the National Weather Service. Rain could move in this weekend.
